Why Xc Services Inc Considers ADT

ADT remains the gold standard for professional monitoring, especially for homeowners who value brand trust and seamless Google integration. The new ADT+ platform finally brings modern smart home automation to a legacy provider. However, the long contracts and high costs mean it's not for everyone – weigh carefully against no-contract alternatives like SimpliSafe. [citation:2][citation:10]

✓ Best for those who want professional installation and Google ecosystem
✓ Consider DIY options to avoid long-term contracts
✓ Read contracts carefully to avoid billing surprises [citation:4]

Frequently Asked Questions

Does ADT require a contract?

For professionally installed systems, yes – typically 36 months (24 months in California). DIY self-installed systems offer month-to-month monitoring with no long-term contract. [citation:1][citation:5]

What is the early termination fee?

For 36-month contracts, ADT charges 75% of the remaining monthly service fees if you cancel early. For example, canceling with 12 months left means paying 75% of those 12 months. [citation:1][citation:5]

Can I keep the equipment if I cancel?

With DIY systems, you own the equipment. With pro-installed systems, equipment is often leased; you may need to return it or pay off the balance. Check your contract. [citation:4]

What is Auto Unlock?

A hands-free feature available with ADT Complete monitoring: when you approach your door, the Google Nest Doorbell recognizes your face and your phone's location confirms it's you – automatically disarming the alarm and unlocking the Yale smart lock. [citation:6]

How does Trusted Neighbor work?

You can grant temporary access to specific individuals (neighbors, dog walkers) using their fingerprint on the Yale Assure Lock 2 Touch, or via temporary access codes – all managed through the ADT+ app. [citation:3]

What happens during a power outage?

The ADT Base has a 24-hour battery backup. Sensors continue operating. Nest cameras store up to one hour of events locally and upload when power returns. Cellular backup keeps monitoring active even without internet. [citation:9]
